After a string of racist, anti-Semitic and anti-gay messages appeared around campus over the past month, Oberlin College canceled classes on Monday for a day of rallies and reflection. Over the past few weeks, Oberlin officials say, messages have appeared around campus denigrating Jews, African Americans and those who are gay. And according to the student newspaper, last month a student said someone made a derogatory remark at him and pushed him to the ground. Then early Monday morning, school officials say, a student reported having seen someone standing near an African culture-themed dorm wearing a white robe and a hood. âItâs not something that weâre interested in sweeping under the rug," says Sean Decatur, dean of Oberlin's College of Arts and Sciences. I think Oberlin as a community wants to be very out in the open that this is something that collectively, as a community, is against our shared values." Oberlin canceled classes, and about 1,000 students gathered on campus for an afternoon rally featuring songs from a marching band and an African dance ensemble. Student speakers said Oberlin should stand against hate speech. Earlier in the day, students had said the school should put greater focus in the curriculum on cultural differences. Second-year student Gabriela Garcia called the incidents scary and said they surprised her. âI learned this in history classesâthat this is something that happened 50 years ago, and not now. But it does happen. It does happen.â? Oberlin security and local police are investigating. The Guardian quotes an Oberlin police officer saying that students were behind the messages, and that the school is dealing with them internally.
